Automotive Injector Pulser Tester KIT
Building Instructions

In this page are detailed instructions
on what the KIT entails, photos and building
instructions. You will get the KIT and CD-ROM building
Manual, with included parts list. This kit contains
current parts. The nominal cost for the parts is
around $14 to $18, plus the cost of this KIT which
includes the 2 PCBs, Front & Back Enclosure,
Metal-Plates, Standoffs, Screws, Tool-Handles and
detailed Manual on CD ROM. The parts list can be
purchased at Mouser,
Digikey,
Newark,
IC Chip Maker or even Amazon.

The Injector Pulset KIT is composed of two PCB,
Custom Designed Plastic Case, Metal-Back-Front
Keypad Plates, Hardware and parts (not
included). Following you can see what the
finished "Injector Pulser Tester" looks like
during and after completing it. This tool is
useful in testing all sorts of fuel injector
related issues, such as injector flow testing,
voltage and current tests, clogged injectors and
air-fuel imbalance issues. See
the Professional Tool on which this KIT is
based on here.

Fig 1: Injector Pulser DRIVER100 PCB
handles the electronics to trigger the
injector properly. This PCB detects injector
current and controls the actual pulse so as
not to saturate the injector-coil-winding. It
also prevents damage to the injector, even if
the injector is shorted or damaged.

Fig 2: The fully assembled
injector pulser PCB (parts not included).
Parts cost is around $10 and the detailed
build-instructions are fully included.
Tech-Support for this KIT is also included.
This PCB is included in the KIT, as well as
the Signal-Button PCB seen below.

Fig 3: Injector pulser INJPLSR-1000
PCB. This PCB circuit is in charged of
generating the control signal to the DRIVER100
board. This kit was developed using through
hole manufacturing for easy of build by you,
the inventor. It employs various chips and
transistors for it's operation. Detailed
instructions are provided with the kit's
CD-ROM manual on a pdf file book. Parts are
not included. A parts list is included in the
manual. The parts cost is around $8. This is a
$480.00 tool when completed.

Fig 4: Only 3 wires join the
DRIVER100 and the INJPLSR1000 board; the 5
volt reference, Ground and signal or pulse
wire. This simple arrangement allows for
modularity in case of repairs and isolation
from the driver circuit. A few simple parts
readily available are needed at a max cost of
$14 to $18 for both. Keep in mind that this is
a $480+
piece of equipment.

Fig 5: Closer view of the
important link between the two boards. These 2
PCBs are included on the kit. The parts (not
included) amount to no more than $14 to $18
worth for a dedicated injector pulser valued
at a few hundred. This pulser will give you
continuous pulse, 5, 10 and 15 mSec pulses at
1, 2, 4, 10 and continuous pulses. This is an
exacting level of testing not available in any
tool today.

Fig 6: These are the INCLUDED
brass standoffs. These are the pillars of
building the injector pulser and are included,
12 of them. These standoffs are attached to
the metal plates. The template for the metal
plates is included in the CD ROM. The plastic
front and back enclosure is also included.

and INJPLSR1000 PCBs attached to each other
with the INCLUDED standoffs. This setup is
then bolted to the metal plates next, that are
also attached to the plastic enclosure.

Fig 8: Detailed photos of the
PCBs attached to each other. Proper length
standoffs are included in the KIT.

Fig 9: Plastic Enclosure front
and back plates are included in the KIT. These
in turn are attached to the metal plates. The
PCB, Enclosure and Metal plates are all bolted
or binded together to form a strong tool.

Fig 10: Front keypad metal
plate and back plate attached to the Plastic
PCB. These two plates form a bonded attachment
that becomes very strong together. The
electronics are well protected. We ran many
tests that made us finally keep this design.
These plastic enclosure and plate is custom
designed.

PRINTABLE layout. It is concluded in the CD
ROM with the KIT. You then can print it and
glue to the metal front plate. (the do
not print watermark is not in the CD ROM
version).

Fig 17: This is what the Professional WOW
Injector Pulser looks like. This KIT is
based on this professional tool. The
difference is that the Professional
Tool uses top-notch parts. Not all IC
chips are the same. We go through great
lengths to make sure our Professionally made
tools are the best made. But, if you don't
want to spend over $400, this KIT is the way
to go. More building details are provided in
the included CD ROM.
